This stacked bar chart shows the distribution of passenger ratings across different categories (such as seat comfort, cabin staff service, and food) for various airlines. Each horizontal bar represents an airline, with colored segments showing the percentage of reviews for each rating level. The visualization uses d3.stack and d3.scaleOrdinal to create the stacked segments, with d3.axisBottom and d3.axisLeft for the axes. Hovering over a segment triggers a tooltip displaying the exact percentage for that rating category, implemented via mouseover/mousemove events. The data comes from a CSV of airline reviews, and the SVG rendering uses custom fonts from Yanone Kaffeesatz and Sofia.

task-8-Q3

This stacked bar chart displays customer satisfaction ratings for six airlines, broken into five score ranges from “Below 5” to “Above 8.5.” Each horizontal bar shows the proportional share of ratings in each category, with the x-axis labeled as a percentage. The visualization uses d3.csv to load the data and d3.stack with d3.scaleBand and d3.scaleLinear to compute and position the stacked rectangles, while d3.axisBottom and d3.axisLeft render the axes. A color legend below the chart maps each rating range to its corresponding fill color.

This stacked bar chart displays customer satisfaction ratings for six airlines, broken into five rating categories from "Below 5" to "Above 8.5" across a horizontal percentage scale. D3.js (v7) fetches the CSV data via `d3.csv()`, then uses `d3.stack()` with `d3.scaleOrdinal` for color coding, `d3.scaleLinear` for the x-axis, and `d3.scaleBand` for the y-axis to render the SVG bars. Each airline’s proportional distribution of ratings is shown as stacked segments, with a legend below clarifying the color-to-rating mapping.

Fork of Activity6_Task2

This stacked bar chart visualizes the percentage distribution of airline ratings across different genres. Each bar represents a genre, with colored segments showing the proportion of each rating level, summing to 100%. Hovering over a segment displays a tooltip with the exact percentage. The visualization uses d3.v7 with SVG rendering, employing `d3.stack()` for data stacking, `d3.scaleOrdinal()` for colors, and `d3.axisBottom()` for the percentage axis.

task 8 question 2.2

A stacked horizontal bar chart shows the proportion of ratings (below 4, 4-5, 5-6, 6-7, 7-8, above 8) for six food categories, with each bar segmented by rating range. The visualization uses D3.js v7 with SVG rendering, employing d3.stack() to aggregate the data, d3.scaleBand() for the category axis, d3.scaleLinear() for the percentage axis, and d3.scaleOrdinal() for color encoding. Interactive tooltips display the exact percentage of each rating segment on hover, using event listeners and d3.format() to present values. The data is loaded from a CSV file containing pre-computed proportions.

Activity6_Question2

This stacked bar chart shows the percentage distribution of five rating levels across seven restaurants, using horizontally oriented bars where each segment represents a rating category. The visualization employs d3.stack() to compute stacked series from CSV data, d3.scaleBand() for the categorical y-axis, and d3.scaleLinear() for the percentage x-axis. Color encoding via d3.scaleOrdinal distinguishes rating bins, while mouseover events trigger tooltip displays showing exact percentage values. The SVG rendering includes axis labels, a title, and grid lines, with data sourced from dataQ2.csv.

Task 8 tutorial 2

This stacked bar chart displays the percentage of rating levels for different cosmetic brands, showing how ratings are distributed across categories like "below 5.0" and "above 8.5." The chart uses a horizontal layout where each brand has a single bar divided into colored segments representing rating proportions, with a tooltip revealing exact percentages on hover. Built with D3 v7, the visualization applies `d3.stack()` to process the CSV data, `d3.scaleLinear` and `d3.scaleBand` for axes, and `d3.scaleOrdinal` for color mapping. The SVG rendering includes interactive mouse events for tooltip display, and the code is sourced from a local CSV file.

Activity6_Question2

This stacked horizontal bar chart shows the distribution of ratings for six food categories, from "Below 4" to "Above 8," with each bar segment representing the percentage of ratings in that range. Built with D3 v7, the visualization uses `d3.stack()` to compute the stacked segments, `d3.scaleLinear()` for the x-axis, and `d3.scaleBand()` for the y-axis categories. Hovering over a segment highlights it and displays a tooltip with the exact percentage, while the data is loaded from a local CSV file. The SVG rendering includes custom axis labels and a legend.
